Why is my Samsung AR18BXHQASINEU Air Conditioner not cooling properly?

If your Samsung Air Conditioner isn't cooling well, several factors could be the cause. Check if the temperature setting is too high; if so, lower it below the room temperature. A dirty heat exchanger on either the indoor or outdoor unit can also reduce performance, so clean it. Also, a dirty air filter restricts airflow, so remove and clean it. Make sure that the air inlet or outlet isn't blocked; if it is, turn off the unit, remove the obstruction, and restart. Ensure doors and windows are closed to prevent warm air from entering. Reduce heat sources in the room, such as electronics or computers. If the refrigerant is low due to a leak or long-term use, check for leaks, reseal if necessary, and refill the refrigerant. Finally, ensure the SILENCE function is off, if it is activated.
